Deferred Revenue, Description	Revenue on fixed-price contracts is recorded primarily using the percentage-of-completion (cost-to-cost) method. Revenue and gross margin on fixed-price contracts are subject to revision throughout the lives of the contracts and any required adjustments are made in the period in which the revisions become known. To manage unknown risks, management may use contingency amounts to increase the estimated costs, therefore, lowering the earned revenues until the risks are better identified and quantified or have been mitigated.
